Philo Judaeus De Ebrietate 131

[131] unless indeed as often as servants, and sons, and subjects, are about to approach masters, and parents, and sovereigns, they take care to be sober in order not to offend in either word or deed, lest if they in any respect act as if contemptuous of their rank, they should be punished, or to speak in the most moderate manner, should at least suffer ridicule; and yet any one when about to become the minister of the Ruler and father of the universe, is not then to show himself superior to meat, and drink, and sleep, and all the vulgar necessities of nature, but is to turn aside to luxury and effeminacy, and imitate the life of the intemperate, and having his eyes weighed down with wine, and his head shaking, and bending his neck to one side, and belching from intemperance, and being weak and tottering in his whole body, is in that condition to approach the sacred purifications, and altars, and sacrifices. No: such a man may not without impiety even behold the sacred flame at a distance.
